The metrics for the heat index are tailored for both shady environments and light winds. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Note: The UV index of 7 during September leads to these advisories:
Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
